SPECIFICATION forming part of Letters Patent No. 318,268, dated May 19,1885.

Application ined July 21, 18e-i. (No model.)

`VTo @ZZ whom it may concern:

Be it known that I, WILLIAM J. KRIZ, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inMagazine-Guns, of which the following is a full, clear, and exactdescription, reference being had to the accompanyving drawings, formingpart of this specification, and in which- Figure 1 is a section taken online 1 1, Fig. 11, showing the parts in tiring position, except thehammers are not cocked. Fig. 2 is asimilar view with other parts insection and parts broken away, showing the hammers cocked. Figs. 3, 4,5, 6, 7, and 8 are detail views showing the construction and operationof the breech-bolt, Fig. 3 being a side elevation showing the boltunlocked and the extractor advanced, Figs. 4 and 5 being face views ofthe breech block, showing the breech bolt in locked and unlockedposition, respectively. Figs. 6, 7, and 8 are top views. Fig.'9 is a topView of the bolt for securing the barrels in firing position. Fig. 10 isa transverse section taken on line l0 10, Fig. 1. Fig. 11 is a similarview taken on line 11 11, Fig. 1. Figs. 12 and 13 are longitudinalsections taken through the body of lthe gun on line 12 13, Fig. 11,showing the working parts in elevation. Fig. 14 is a detail top view,part broken away. Fig. 15 is a detail side View, part broken away. Fig.16 is a transverse section taken on line 16 16, Fig. 1. Fig. 17 isatransverse sect-ion of one ofthe hammers, taken on line 17 17, Fig. 1.Fig. 1S is a transverse section of the breech-bolt lever, taken on line18 18, Fig. 12.

My invention relates to abreech-loading and magazine hre-arm; and itconsists in features of novelty hereinafter fully described, and pointedout in the claims.

Referring to the drawings, A represents the barrel of the firearm,having two rifle-bores and two shot-bores, (see Fig. 10,) the latter ofwhich and the lower one of the former are loaded by throwing up thebreech and inserting the cartridges in the ordinary way, and the upperrifle-barrel is loaded from the magazine by an improved device to whichmy invention relates.

B represents part of the stock ofthe rearm, which is hollow, as shown inFigs. 12 and 13, to receive the cartridges.

B represents part of the breech-frame slotted to receive the bolt B2,which holds the barrel in ring position. The form of this bolt is shownin Fig. 9. It has a slot, B3, to receive one of the lugs A ou thebarrel, being considerably longer than the lng, as shown in Fig. 1, toallow the'mcvement of the bolt. The other lug A is notched at A2 toreceive the end of the bolt, and the irst-mentioned lug has a similarnotch to receive the part B4 of the bolt. This bolt is moved back to theposition shown in Fig. 2 to release the barrels by a bifureated lever,B5, pivoted at B6 to the frame B', and engaging with the bolt by itsarms entering slots B7.

B8 represents the fore-end, held in place bya conical pointed bolt, B9,(see Fig. 15,) fitting in a slot in a lug, A3, on the barrel, and havinga spiral spring, B1, located behind it. The piece BS is notched toreceive the lug A3, and has a recess to receive the conical end of thebolt, as shown. This bolt thus holds the foreend to the barrel, butallows its easy removal by simply pulling its outer end down or awayfrom the barrel when it is desired to disconneet-'the barrel from thestock. e pin is held in the lug when the fore-end is removed by a plug,B, through which the stem of the bolt passes' and behind which thespring B1U is located.

C represents the main levers, pivoted at C to the stock B.

I represents the hammers within the stock on shafts I', as usual, onwhich are also the tumblers I, connected to the mainsprings 13 by linksI, the tumblers having projections I5, to which the links are connectedby pins IG. (See Fig. 11.)

I7 represents the triggers engaging with the tumblers, as usual, and lSrepresents the lockplates to which the hammers, tumblers, andmainsprings are secured, and which are made fast to the stock in theordinary manner. The hammers are cocked as the levers C are thrown intothe position shown in Fig. 12 by means of short pins C2 on the levers,that come in contact with the hammers and force them back,

IOO

Fig. "13', and they are then forced from that position to the positionshown by cartridge H,

Fig. 12, by means ot' an arm, J, having a hooked or notched end thatengages with the flange of the cartridge, -as shown. The varm isoperated by means of a crank, J 2, ona shaft,

J', to which the arm is secured, the crank being connected to one of thelevers C by alink,

J3, and pin J4, the pin fitting in a slot, J?, -in the link to allow anecessary play of the lever before the armis operated. As the lever andarm are forced from the position vshown in Fig.13 to that shown in Fig.12, the cartridge is raised, and then as the leverismoved back the armis moved back and 'the cartridge H is forced on vinto the bore v'bythefollowing v means:

. in Fig. 1.

L represents a breech-bolt fitting and supported in the upper part of"the s'to.ek. It has a spiral groove, L', whichreceives ajprojection, Non the upper end o'fjan extension, N', of the lever, to `which the arm Jis yconnected. The extension is dovetailed'into the upper end of thelever, as shown in Fig. 18, so that it shortens up and lengthens out asthe lever is operated, and the breech-boltListhus forced back to theposition shown in Fig. 12 when the lever is opened, and then ias/thelever is closed to the position shown in Fig. 13 the breech-bolt isforced inward, carrying the cartridge H before it,from'thegposition'shown in Fig. 12 to that shown in Fig. `13,:an'd alsoVhen the breech-'bolt lhas reached the limit of its inward movement,`the `lever yis not yet quite closed,-and the Vfurther 'movement ofthelever turns the breech-boltthrough means of the spiral groove L' andY.projection fitting therein, and as it is thus turned lugs L2 thereon.(see Figs. 4, 5, 6, 7, and '8) enter notches in the front wall of thestock, the breech-bolt turning from the position shown in Fig. 5 to thatshown in 4. hen V'the gun is red, the breech-bolt is thus held frombeing forced back by the explosion ofthe cartridge. When the lever isopened again, the first thing done to the breech-bolt 'is tto turn it tounlock it, and then it is 'forced back, as described.

Fitting over and secured tothe inner end of the breech-bolt is a block,O, `having an extension, O', to which is secured an extractonOz, byscrews O3, fitting in slots O4 in the extractor.v The inner end of oneof the screws ts -in a spiral groove, O5, in the breech-bolt, 'turningin the opposite direction Ito that L.'. As the -breechbolt is turned toloe'k'it the extractor isretracted, and as it is turned 'to unlock itthe extractor is forced forward by means Vof the groove O5 and screw'O3and engaged-over the flange of the shell, as shown'in Fig. 3, and

l then as thebreech-bolt is forced back the extractor and shell arecarried back with it to the position shown in Fig. 12, where the shellis thrown out by the next cartridge which is brought up, as described,by the arm J. As the breech-bolt is moved forward the extractor isforcedbackthe distance ofthe length of the slots'O4'by the screw workingin the groove O5. The arm J works in a slot, A6, of the stock B, and itwill be seen that it will strike the `next cartridge on its downwardmovement, and for this reason it is made quite thin, as shown in Fig.11, so that when it strikes the round cartridge it will springv to oneside'and pass 'under it.

As the cartridges ascend the incline A4 they are held from lateralmovement by plates Al, located in the hollow stock, (see Fig. 11,)between Which they are directed by springs l?, secured to the interiorof the stock.

U represents the firing-pins, of lwhich there are four-one for eachbore-as shoWnin'Fi gs. ,1, 2, and 16, two being struck by each hammer bymeans of adjustable blocks' V, (one on each hammer,) which are raised orlowered, according to which pins are to be struck, by v small levers ortriggers V', pivoted to the pintles of the main levers andconnected bymeans of links72 to the stems V3 of the blocks, which t in the holloworgroovcd hammers, as shown in Figs. 2 and 17. By forcing the levers ortriggers into the position shown in Fig. l the blocks will be raised andwill strike the upper .r'ing-pins, and then, by forcing the levers ortriggers into the position shown in Fig. 2, the blocks will be pulleddown and will strike the lower firing-pins, being heldin either positionby springs Y, whose heads V' engage in recesses V4 in the blocks.

Vlf it is desired to secure the hammers in their cocked position toavoid any accidental discharge of the gun, it may be done'by a slidingblock, W, held in the upper part of `the interior of the stock by aprojection, with a head, W', on its outer end that ts in a slot, W2, ofthe stock. (See Figs. 1, 2, and 14.) By sliding the block to theposition shown in Fig. 2 it will be seen that it will engage with the'upper ends of the hammers and prevent their operation. The block ismoved by simply pushing on the head W'.

By the use of the slot J5 in the link J3, the
